Which is the highest spoken languages in world?

The highest spoken language in the world is Mandarin Chinese, with approximately 1.1 billion native speakers.

It's important to note that "highest spoken" can be interpreted in different ways. You could also be asking about:

* Total speakers: This includes both native and non-native speakers. In this case, English would likely be the highest, with an estimated 1.5 billion speakers globally.

* Second language speakers: In this case, English is also the most commonly spoken second language.

So, while Mandarin Chinese has the most native speakers, English is likely the most widely spoken language overall.
